The British won all of the starting goals but didn't achieve any of the later puntive goals, due to being more concerned about Europe and having already cleaned up out of the Napoleonic Wars.
So the British won a clear victory but one ended by a settlement rather than a diktat. Largely because London wasn't really bent on a diktat.
Canada not only survived but was strengthened and didn't lose an inch of territory. Decisive victory.
The US gained nothing at Canada's expense and the issue of respecting US neutrality and the impressment of seamen weren't even mentioned in the settlement. Having failed to achieve any of the goals the US lost.
Zyzzyva, actually the British decision was made too late to avert war because they concluded(correctly) that the French would not honor their agreement with the US but didn't bother to rush their own proposal over because apparently they never realized that the US might not realize this.
Umbric, since the US abandoned all interest in the impressment of seamen or the ability to trade freely through blockades in time of war, both of which were irrelevant once Napoleon was beaten, why would anyone else need to talk about those subjects? As for naval battles, the British hunted down or trapped the entire US Navy and the British blockade threatened to divide the nation so a few brave ship to ship actions, invariably involving American ships against inferior British ships, doesn't really matter much.
It's true, by the way. Five of the seven American frigates were specially designed and built to be bigger, better armed and much sturdier than the British frigates and did well in action accordingly. The other two were a captured French frigate(!) and the Chesapeake, the sixth frigate which a fool resenting the designer of the other five frigates deliberately built to normal standards, which is to say standards inferior to the other five. As a result USS Chesapeake was lost in its first action of the war.
As an interesting note it may not have been size nor armament but structural design and strength which made the American frigates so much stronger relative to their size.
